This question asks to identify the product formed when barium chloride reacts with aluminium sulphate. This is a double displacement reaction, where the cations and anions of two reactants swap places. We need to determine the solubility of the products formed to identify the correct option.
D) Solid BaSO₄ is formed. This is correct because barium sulphate is insoluble in water and precipitates out as a solid in this double displacement reaction.
The question asks to identify which part of the Himalayas is known as the Great or Inner Himalayas or the Himadri. This requires knowledge of the different parallel ranges of the Himalayas and their respective names.
Correct Option: A) The northern-most range of the Himalayas is known as the Great or Inner Himalayas or the Himadri. This range is the most continuous and has the highest peaks.
The question asks to identify the state with the highest percentage of poor people according to NITI Aayog's Multidimensional Poverty Index (MPI) – 2021. This requires knowledge of the findings of the specific report.
A) Bihar — As per NITI Aayog’s Multidimensional Poverty Index (MPI) – 2021, Bihar had the highest percentage (51.91%) of its population identified as multidimensionally poor.
Study the given diagram carefully and answer the question. The numbers in different sections indicate the number of persons. The circle represents ‘teachers’, the square represents ‘men’, and the triangle represents ‘post graduates’.
How many men are there who are NEITHER teachers NOR post graduates?
Correct Option: D) 1
To arrange the given non-metals (O, Te, S, Se) in increasing order of their electronegativity, we need to recall the periodic trends for electronegativity. Electronegativity generally increases across a period from left to right and decreases down a group in the periodic table.
Correct Option: D) Te < Se < S < O
Five friends P, M, Q, S and J have their shops in the same market. P’s shop is to the north of M’s shop, which is to the west of Q’s shop, which is to the west of S’s shop. S has his shop to the north of J’s shop. Because of some reasons, M and J have exchanged their shops.
What is the direction of J’s shop with respect to P’s shop now?
This is a direction and distance reasoning problem. We need to establish the initial relative positions of the shops and then determine the new positions after the exchange to find the final direction.
Based on the above, the initial arrangement can be visualized as:
P
|
M --- Q --- S
|
J"M and J have exchanged their shops." This means M moves to J's original position, and J moves to M's original position.
The new arrangement looks like this:
P
|
J --- Q --- S
|
MP's shop is at the top. J's shop is now at the position previously occupied by M, which is directly south of P's shop.
C) South. After the exchange, J's shop is now where M's shop used to be. Since P's shop was to the north of M's shop, J's shop is now to the south of P's shop.
Five persons, Pravalika, Roshan, Tarak, Vitika and Yadhu, live on five different floors of the same building. The lowermost floor in the building is numbered 1, the floor above it is numbered 2, and so on till the topmost floor is numbered 5. Vitika lives on the floor immediately below Yadhu. Pravalika lives on the floor immediately above Tarak. Roshan lives on the floor immediately above Pravalika. Yadhu lives on the floor immediately below Tarak.
Who lives on the third floor?
This is a logical reasoning problem involving arrangement. We need to deduce the living arrangement of five people on five different floors based on the given clues. We will use a step-by-step method to build the floor arrangement.
Let's combine the clues to form a single sequence.
Since there are 5 people and 5 floors, and we have a complete sequence of 5 people, we can directly assign them to the floors from top to bottom or bottom to top.
A) Tarak — As derived from the step-by-step arrangement, Tarak lives on the third floor.
The question asks to identify which of the given languages is NOT yet recognized as a Classical Language of India as of 2022. This requires knowledge of the languages that have received classical status from the Government of India.
Correct Option: A) Marathi is not among the six languages that have been designated as Classical Languages of India as of 2022. While Marathi has a rich history and literary tradition, it has not yet received this official status.
If x3y : xy :: xy : a, then which of the options below gives the value of a?
\(\frac{y^{2}}{x}\)
\(\frac{y^{2}}{x^{2}}\)
\(\frac{y}{x}\)
\(\frac{y}{x^{2}}\)
The problem presents a proportion involving algebraic expressions. We need to find the value of 'a' by applying the fundamental property of proportions: the product of the means equals the product of the extremes.
Correct Option: C) \(\frac{y}{x}\)
The sales of three companies X, Y and Z in different years are shown in the following graph. Study the graph and answer the question.
Which company has the highest total sales for the period from year 1996 to 1998? By what percentage is the sales of company Z more than company Y in the year 1997?
To solve this question, we need to analyze the graph provided and calculate the total sales for each company from 1996 to 1998. Additionally, we will determine the percentage difference in sales between companies Z and Y in 1997.
Thus, the percentage increase is 50%, but this does not match any options. However, option D correctly identifies company Z as having more sales.
Correct Option: D) Z, 20%
